FICM rollback MPG's

Where do I find the EBP? Would it show up on a code reader? Yep. Stuck at 15.4 mpg with the programer. My '04's would run in the 18's on the same roads with the programer.

Oddly, the EBP never seems to set a DTC, even when clogged. The sensor is located on the Drivers side of the engine and connects to a tube which runs to the front of the driver's side exhaust manifold. It's pretty easy to find. Let me know if you have any difficulty locating it and I'll see if I can get a diagram of it for you.

usually located on top(bolted to) of the thermostat housing, hope this helps....i to will looking at my sensor, haven`t seen the improvements i was hoping for in the mpg after doing ficm reprogram and ecm/tcm rollback and new custom tunes. the tube is clear, may just replace sensor and try that(not expensive part)....other then that, truck works awsome....thanks Bill
